Abstract
The utility model discloses a kind of drill bits using multitool access slot, including cutter shaft and cutter head, the cutter head is correspondingly arranged in cutter shaft one end, the cutter head includes the first cutter head and the second cutter head, diameter of the diameter of first cutter head less than the second cutter head, the diameter of second cutter head is less than the diameter of cutter shaft, the first fluting is correspondingly arranged on first cutter head, the second fluting is correspondingly arranged on second cutter head, first fluting is using the minimum diameter of drill bit as core thickness, second fluting is using the maximum gauge of drill bit as core thickness, the smooth connection in connecting pin of first fluting and the second fluting.The utility model is slotted using multitool, both can guarantee that the cutting of cutter apex was brisk, chip removal is smooth, and can guarantee the rigidity of cutter, intensity.
Description
Technical field
The utility model relates to be machined to use cutter field, more particularly to a kind of drill bit using multitool access slot.
Background technique
It is conventional during making cutter for step drop in nonstandard cutter up to 3 times and 3 times or more of drill bit
Fluting can make cutter root (at big outer diameter) core so as to cause cutter poor rigidity, be easy to happen fracture, influence cutter thicker than small
Service life.As only slotted using the mode of grooving for promoting geometric angle, the entire groove profile of cutter can be made to change, chip space meeting
Greatly, tread can be small, and cutter rigidly can be insufficient, and tipping or breaking easily occurs.
Utility model content
The utility model mainly solving the technical problems that provide it is a kind of using multitool slot, both can guarantee that cutter apex was cut
Cut brisk, chip removal is smooth, and can guarantee the drill bit using multitool access slot of the rigidity of cutter, intensity.
In order to solve the above technical problems, the technical solution that the utility model uses is: providing and a kind of connect using multitool
The drill bit of slot, including cutter shaft and cutter head, the cutter head are correspondingly arranged in cutter shaft one end, and the cutter head includes the first cutter head and second
Cutter head, less than the diameter of the second cutter head, the diameter of second cutter head is less than for the diameter of first cutter head
The diameter of cutter shaft is correspondingly arranged on the first fluting on first cutter head, is correspondingly arranged on second on second cutter head
Fluting, first fluting are using the minimum diameter of drill bit as core thickness, and second fluting is using the maximum gauge of drill bit as core
Thickness, the smooth connection in connecting pin of first fluting and the second fluting.
In one preferred embodiment of the utility model, be correspondingly arranged on first cutter head there are two first fluting.
In one preferred embodiment of the utility model, the first fluting helically structure setting.
In one preferred embodiment of the utility model, one end of first fluting is correspondingly arranged in the second fluting.
In one preferred embodiment of the utility model, it is described second fluting setting there are two equally twist structure with
First fluting is arranged in a one-to-one correspondence.
In one preferred embodiment of the utility model, one end of second fluting is correspondingly arranged on cutter shaft.
The beneficial effects of the utility model are: the utility model is slotted using multitool, it both can guarantee that the cutting of cutter apex was light
Fastly, chip removal is smooth, and can guarantee the rigidity of cutter, intensity.
Detailed description of the invention
Fig. 1 is the front view of drill bit one preferred embodiment of the utility model using multitool access slot；
Fig. 2 is the left view of Fig. 1.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Fig. 1 combination Fig. 2 is please referred to, the utility model embodiment includes: a kind of drill bit using multitool access slot, including cutter shaft
1 and cutter head, the cutter head is correspondingly arranged in 1 one end of cutter shaft, and the cutter head includes the first cutter head 2 and the second cutter head 3, and described first
For the diameter of cutter head 2 less than the diameter of the second cutter head 3, the diameter of second cutter head 3 is less than the diameter of cutter shaft 1
Size is correspondingly arranged on the first fluting 4 on first cutter head 2, the second fluting 5, institute is correspondingly arranged on second cutter head 3
Stating the first fluting 4 is using the minimum diameter of drill bit as core thickness, and second fluting 5 is using the maximum gauge of drill bit as core thickness, institute
The smooth connection in connecting pin of the first fluting 4 and the second fluting 5 is stated, is correspondingly arranged that there are two the first flutings on first cutter head 2
4, one end of the 4 helically structure setting of the first fluting, first fluting 4 is correspondingly arranged in the second fluting 5, and described the
There are two two flutings, 5 settings, and equally twist structure is arranged in a one-to-one correspondence with first fluting 4, second fluting 5
One end is correspondingly arranged on cutter shaft 1.
It when processing, is slotted using multitool, for example two knives is divided to slot, the first knife is slotted c, a on the basis of cutter minimum diameter
It is the core thickness after the first knife fluting；Second knife is slotted d on the basis of cutter maximum gauge, and b is that the core after the second knife fluting is thick；Together
When ensure the smooth connection of two bar grooves.
The utility model is a kind of drill bit using multitool access slot, and the utility model is slotted using multitool, both can guarantee knife
Tool apex cutting is brisk, and chip removal is smooth, and can guarantee the rigidity of cutter, intensity.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
